It happens from the moment I start with the screen saver, the machine is a not to be logged on to Windows or Internet, eventually becomes less a problem when the screen and M/c for awhile, but never seems to completely disappear. What I want to know is there anything else he can be cured by buying a new monitor? any info would be greatly appreciated

Hello

1. you hear the music when the blackscreen appears?
2. did you last changes made before the problem started?
3. have you installed any third-party screen saver?

Try the following steps:

Step 1: disable screen saver and check if it makes a difference.

Refer to this link for help:
Enable or disable the screen saver

Step 2: update the drivers for your graphics card.

Follow these steps to update the drivers manually:
a. open the Manager of devices by clicking the Start button, click Control Panel, click System and security, and then, under system, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
b. in the list of hardware categories, click on the graphics card and then double-click the device name.
c. click on the driver tab, click Update driver and then follow the instructions. If you are prompted for an administrator password or a confirmation, type the password or provide

  • Screen goes black randomly and the mouse resumed normal functions

    My screen started to be empty at random. It seems to do a quick fade to black as if the power manager is turn off the screen. The PC stops not is and shake the mouse he brings.

    I checked my video driver, malware, power settings (currently any screen power off or power off is disabled). Went to powercfg and checked last wake-up factor, but it does not list everything. If it's just a removal of the power management screen, not sure it would be listed here because it is not a full power down.

    Is there a way to tell if it is the power Division of the screen Manager and if so, what is the cause of do?

    I begin to suspect my keyboard although it's just a hunch. It's an old v1.0 MS Comfort Curve Keyboard 2000. Keys become a little sticky, although there is no any button power on this issue (like the old buttons suspend) and from the keyboard Manager, he was very much tied to her. According to me, it came with a mouse since I replaced it with a mouse Spawn CMStorm. Perhaps there is an intervention of the strange?

    Original title: off dead zone screen

    It doesn't seem to be a thermal problem of graphics card. Seems not be related to what application is running, or at room temperature and it seems to come back with the movement of the mouse (and stay off without moving the mouse) this is why I suspect something to do with power management.

    Any suggestions?

    It looks like the mouse driver or firmware causing trouble...

  • iPhone 6 screen goes black randomly. Hard reboot solves the problem temporarily

    Hi all

    My iPhone 6 screen goes black randomly (usually during sleep) and when it happens, the fact response to touch or no sound. I know that the phone is on because I can always call another phone and it sounds on the line, but as I said the iPhone does not ring. Hard reboot (press home + power button for a while) will not solve the problem immediately after the restart, but after some time (hours or days), it goes black again and I have to do the same thing.

    No idea why this is happening? Is it a software or a hardware problem?  I'm really curious to know how to restart the phone resolves the problem.

    I am not able to take it to the bar of the kind of these days because of my busy schedule. I wonder what they need to replace when I take it to the store.

    Please, share your ideas.

    Thank you

    Sounds like a problem of software for me, especially because it forces is a troubleshooting step software, and you say that solved the problem (of least temporarily).

    However, I still think that the Genius Bar would be a good idea. They have access to diagnoses that are not accessible by the user, who can easily identify which applications or processes are causing the problem. I think that they can also do this by phone, but I rarely call support so I am not sure.

  • Spectrum x 360: screen goes black randomly when on battery and some energy-saving options enabled

    Hello everyone,

    I bought this fantastic machine called spectrum x 360 and I love it.

    Unfortunately since the early days I'm facing what I think it's a problem of driver/software (not the related material).

    This problem only occurs when I'm on Windows, not in the bios or at the startup. JUST IN Windows envinroment, especially after the login, and when the computer was turned off. Sometimes when I use it after a while, randomly.
    This occurs only when the spectrum is on battery. The problem does not appear on AC adapter.

    Problem: the screen goes black randomly for a few seconds and then reappear, sometimes the entire image on the right slide and there is a part that looks like yellow and corrupt, then goes black and reappears.

    Windows Version: I'm on Windows Home 64 bit, build 14393.321 10 (update of the anniversary).

    The entire screen works fine for normal operations, no artifacts.

    Replication of the problem
    Initially, I was able to reproduce the problem with the driver build 4360 (which is the version of the driver from the HP site). Whenever I loaded the home page of youtube and the banner has started playing on the screen went black sistematicly.
    Then I updated the GPU driver through the Device Manager, which has improved my GPU driver to 21.20.16.4494, as of July 25, 2016 and the problem happens much more rarely.
    Now I am facing this problem again but Edge works correctly and is not the cause of the problem, it can appear even when I don't do anything with the PC.

    I noticed this problem appears when saving options are enabled for the Intel GPU (I'm trying to translate this to English because the GPU driver Panel is in Italian):

    -update panel houses;
    -advanced mode; energy saving

    If I disable these options, the problem does not appear or, better, for I've tested so far, he could not displayed when options are not in market, but I have not tested this very long to be sure.

    In my opinion, there is a bug in the display driver, or some customizations made by HP causes problems with the driver.
    The rest of the computer works correctly.
    Any idea to solve this problem? Or should I keep these options turned off power saving?

    Hi, thanks for your help.

    I have a passion for COMPUTING and ex-computer SCIENTIST, I am familiar in surveys on hardware/software questions and hope that this post will help some users get rid of this problem.
    Black screens and screen corruption has been issued by the option called "auto refresh Panel" energy saving.
    I did a lot of hours on battery (condition where this pop ups problem) in these days and the problem didn't show when it was turned off.
    To verify that I tried to activate "Panel options self-identity" in certain occasions and, at random, on the first boot of the machine (after being turned off) the problem arises again.
    It certainly is a problem with this energy-saving option.
    Now everything works fine.
    If the problem appears again, I will post more information.
    Thank you for your support.

    I think it would be useful to stick this post on top in this section of the forum, to be useful to other users and being more visible.

  • screen goes black instead of the newspaper showing

    Hi, I had a problem enough. This has happened right after that I restarted my computer.

    Load Windows, but just like your so-called self connection, screen goes black, not market not to answer any type of order. The screen is not active, it's still reciving a signal, it shows just a black screen.

    So I thought just run in safe mode and restore the computer to a point a few days back, but as I try to load safe mode, it gets stuck on crcdisk.

    So I figure I would use the vista cd to check for errors. The cd loads but just as it is supposed to show "icons" that simply shows bakground, don't smile icons.

    I had a problem of smililair once, but then the computer started just after 5 min of blackscreen, at this time there, I figured a windows update to be the cause(not sure though) (I also did research of virus lying right there, but everything seemed fine).

    I don't know how, but I left my computer on for the night, showing just a black screen. But in the morning he show would screen checking disk errors, it was 100% complete and says it all was ok, but it got stuck on this screen.

    Advice, ideas, suggestions?

    Hello

    You can try the following steps and check:

    Step 1:

    Unplug all external devices and tries to boot into normal mode and check if the problem occurs.

    Step 2:

    Since you can not boot from an Installation of Vista disc for troubleshooting more away, you can try to boot from the system pre-installed on your computer recovery options and perform a startup repair. If that fails, then try a system restore and check.

    For more information, see the link:

  • Screen goes black randomly

    The issue I'm having is that my Vaio VPCEE32FX Laptop screen keeps going black. However, I see a faint image on the screen if I shine a flashlight on the subject. Also, I can get the screen to return to normal if I press hard directly on the cell to the right of the track key (where you would have your right Palm while typing) while lifting the lower left corner of the laptop (kindof bending the laptop a bit). I heard that the inverter can fail however when I 'bend' the laptop to 'solve' the problem is far away where the inverter is. Could I have a loose fitting. Y at - it something near the pad mouse that could become loose. I check the hard drive and it is correctly fixed. Help, please!

  • Screen goes black and only the mouse pointer visible to the windows xp screen

    My computer has used to work without problems.  Now, when I start it upward, to the Windows XP start screen, the screen turns off and all that is visible is the mouse pointer.  I tried to start safe mode, and it does give me even the option - not even if I press F8 at startup upward.  What is the problem with my computer and what can do?

    Thanks for your answers, Dena and Jojih.

    The screen went black and all I could see was the mouse pointer.  There is no ameioration or changes on the hardware of all kinds.  I wonder if one of my employees has a virus on the computer.  I could not do in safe mode, even if I tried to press F8.  If I put in the Windows XP CD, the screen would go black after that he loaded the system files, just like at the start of Windows XP.  So I used Acronis PC Backup and Recovery and make a recovery disc and used to reformat the hard drive and then I reinstalled Windows XP.  Everything has been great to work for.

  • Locking of the blackBerry Smartphone screen/keyboard keeps activating while the phone is in use.

    I have a Blackberry 9810 "BOLD" and the screen/keyboard lock feature is always activate itself, even when I'm in the middle to send him a text or using the phone. Yesterday, it happened while I was talking on the phone and he cut the call. I can't find an option on my phone to activate switch. How can I solve this problem, because it's practically what makes my phone useless.

    Hello

    Well, first of all... No... no 'BB support' can answer you here. This is because, when they gave to you when you register on this site, this site has nothing to do with any formal support any. On the contrary, it is a community of users where volunteers try to troubleshoot other kind souls to the best of their ability. Unfortunately, no response would mean that anyone who took the time to read your post has something useful to you.

    From what you describe, I would infer that there is a wrong application behave which interferes with the function of locking, or maybe your operating system is somehow corrupted, or maybe a combination of the two. What I recommend is the following:

    1. Reload your own OS and as "skeleton" as possible (for example, whatever it is optional, let power off)
    2. If the problem immediately presented, then repeat step 1, but with an OS different package... maybe there's a bug in the specific operating system you run.
    3. If the problem does not immediately, then run for maybe a week-long enough to be sure that the behavior will not occur.
    4. If the behavior does not after a week, add just one thing (just one... no matter how tempting it is to add more!)
    5. Repeat steps 3 and 4 until the behavior is, how well do you know the culprit
    6. If the behavior does not, then you know that reloading the OS or switch to another operating system package was the cure.

    If none of this he healed, then you will have a physical hardware problem for which assessment in the hand by a qualified material is of course necessary. If you are under warranty, you seeking your warranty provider - normally your place of origin of the purchase, your provider of mobile service or one authorized service center (it varies by location, but you should have received the documentation at the front that tells you exactly how to use your warranty).

    Good luck!

  • My screen goes black, but is still on. My computer shuts down everything he does and I have to restart so that it become operational.

    I said the video card is corrupted or is overheating.
    The screen goes black randomly. Sometimes 2 minutes playing or until hours later. Sometimes it will not.

    Connect the computer to another monitor. If the problems are gone, replace the original monitor. If the problems persist, then you have hardware problems on your computer. You can troubleshoot the hardware yourself:

    This includes exchanging the video card for a well-known work.

    On tests of hardware failures often alleged swapping parts by parts checked. If you can not do the test yourself and/or are uncomfortable opening your computer, take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad). If possible, have all your data backed up before taking the machine into a shop.
